Claims.

This invention relates to certain improvements in hair waving pads foruse where'a pre-formed tress of hair is subjected to the action of anexothermic material contained within the pad, which 5 exothermicmaterial, when moistened, will, of itself, generate heat suflicient toimpart a so-called permanent wave to the pre-formed tress.

The object of my invention is to materially reduce the expense ofpermanently waving hair by providing a wrapper of flexible imperviousmaterial and its inner hair protecting flap of flexible material, whichwrapper and flap may be used over and over again with successiveexothermic material containing envelopes.

My invention consists in a hair waving pad comprising the followingelements: an outer wrapper, an inner flap carried thereby, a separateexothermic material containing envelope, and an absorbent flap carriedthereby, the envelope and absorbent flap being removably insertedbetween the wrapper and its inner flap before the pad is wrapped aroundthe pre-formed tress.

Practical embodiments of my invention are represented in theaccompanying drawing in which Fig. 1 represents an inside plan view ofthe outer wrapper with one form of the inner flap carried thereby;

Fig. 2 represents a similar view with another form of. inner flap;

Fig. 3 represents an inside plan view of the temporarily sealedpre-perforated exothermic material containing envelope and its absorbentflap carried thereby;

Fig. 4 represents an outside view of the pad in 0 its wrapped andsecured position around a preformed tress; .and

Fig. 5 represents one form of clip for holding the outer portion of thepad in its wrapped condition.

The outer wrapper I of the hair waving pad is adapted for repeated useand is of flexible impervious and durable material which will not bedestroyed or its efficiency impaired by repeated use in connection withsuccessive exothermic material containing packs.

This impervious outer wrapper I is preferably made of oil silk,rubberized or resinized fabric, etc. In the form shown in Fig. 1, theinner flap 2, which is carried by the impervious outer wrapper i, is ofthe same material as the outer wrapper and is perforated, as shown at 3.In the form shown in Fig. 2, the inner flap 4, carried by the imperviousouter wrapper l, is, of some pervious material, such as cotton cloth,and is imperiorated.

The inner flap may be an extension of the outer wrapper and folded overon to the same, as shown in Fig. 1, or it may be a separate piece ofmaterial permanently secured to the outer wrapper, as by stitching, asshown in Fig. 2, where the 5 secured end of the flap is shown asinserted between the wrapper and the folded over edge of the same.

The pack which contains the exothermic material is herein shown as anenvelope 5 of imper- 1o vious material, as foil, containing theexothermic material, the face of the envelope being pre-perforated, asshown at 6, the perforations being temporarily sealed by suitable means,such, for instance, as a removable sheet I of impervious 15 material, asfoil, adhered to the perforated face of the envelope by an adhesive, aspetroleum jelly, which will not injuriously affect the pre-formed hairtress or the action of the exothermic material when the pad is in use.One edge of this 20 sealing sheet I may be extended, as shown at 8,beyond the envelope 5 for facilitating the strippingof the sealing sheetfrom the perforated face of the envelope before the pad is to be used.

The flap 9 of absorbent material is herein shown 25 as permanentlysecured along one of its edges to one of the edges of the envelope, asby staples.

The usual self-locking clamp 10 is provided for securing the inner endof the pad in its wrapped position snugly around the pre-formed tress,and 30 stripped from the perforated face of the envelope 40 L 5, leavingthe perforations exposed. The absorbent flap 9 is moistened by water. ora suitable wav- 1 ing solution and folded over on to the perforated faceof the envelope 5. The envelope 5 and flap 9 are then inserted betweenthe outer, wrapper .l 45 and-the folded inner flap 2. The whole is thenwrapped around the pre-formed tress with the inner flap located betweenthe envelope and tress. The wrapped pad is then secured in position bythe clamp Land clip II. The exothermic action 50 of the material withinthe envelope will develop heat sufficient to produce a so-calledpermanent wave. After the wave has been completed, the clamp H and clipIn may be removed, thereby permitting the pad to be unwrapped. The usedenvelope 5 and its absorbent flap 9 may then be removed from the outerwrapper I and its inner flap 2. The wrapper and its flap will then beready for use in connection with an unused en- 5 velope and itsabsorbent flap.

While I have described my invention in connection with a spiral woundtress, it is to be understood that it would be equally applicable foruse in connection with a croquignole wound tress.

10 It is also.evident that various changes may be resorted to in theconstruction, form, and arrangement of the several parts withoutdeparting from the spirit and scope of my invention, hence I do not wishto limit myself to the particular embodiments herein set forth.

What I claim is:

1. In a hair waving pad, an outer flexible wrapper of relatively durablematerial adapted for repeated use, and an exothermic material containingflexible envelope forming a discardable element for single use only, theenvelope being adapted to being removably placed in operative positionupon the outer wrapper before the pad is applied to the hair tress.

' 2. In a'hair waving pad, an outer flexible wrapper of relativelydurable material adapted for repeated use, and an exothermic materialcontaining flexible envelope and a flexible absorbent flap formingtogether a discardable unit for single use only, the envelope and,absorbent flap being adapted to be removably placed in operativeposition upon the outer wrapper before the pad is applied to the hairtress.

3. In a hair waving pad, an outer flexible wrapper and an inner flexiblehair protecting flap forming together a permanent unit, and anexothermic material containing flexible envelope and a flexibleabsorbent flap forming together a discardable unit for single use only,the envelope and absorbent flap being adapted to be removably insertedbetween the outer wrapper and its inner hair protecting flap before thepad is applied to the hair tress.

4. In a hair waving pad, an outer flexible wrapper and an inner flexiblehair protecting flap forming together a permanent unit, and anexothermic material containing flexible envelope and a flexibleabsorbent flap forming together a discardable unit for single use only,the envelope and absorbent flap being adapted to be removably insertedbetween the outer wrapper and its inner hair protecting flap before thepad is applied to the hair tress, said inner hair protecting flap beingperforated.

5. In a hair waving pad, an outer flexible wrapper and an inner flexiblehair protecting flap forming together a permanent unit, and anexothermic material containing flexible envelope and a flexibleabsorbent flap forming together a discardable unit for single use only,the envelope and absorbent flap being adapted to be removably insertedbetween the outer wrapper and its inner hair protecting flap before thepad is applied to the hair tress, said inner hair protecting flap beingof pervious material.
